Energy Storage and Conversion

This paper presents a comprehensive techno-economic and environmental assessment of a grid-connected hybrid renewable energy system (HRES) integrating photovoltaic (PV), wind turbine (WT), and fuel cell (FC) technologies for a case study in Dakhla, Morocco. A detailed modeling framework is developed, including renewable generation, electrolyzer operation, hydrogen storage, and fuel cell conversio…

This study looks at the resilience and cross-region fidelity of a HRES (Hybrid Renewable Energy Systems) across multiple climates in Africa. The study modelled the systems with a PSO (Particle Swarm Optimization) algorithm in MATLAB (Matrix Laboratory). “Large-scale transferability” refers to the system’s capacity maintained against tight acceptance criteria. Normalized load curves were used to d…

Open solar dehydration has been used traditionally to remove moisture from culinary leaves in order to preserve their medicinal and nutritional qualities. This paper investigates the performance of a converted family-size (27 L) solar box cooker for solar dehydration of culinary leaves (Bay, Sweet, and Greek Basil and Common Sage). The investigation was carried out over the three month period fro…

This paper investigates the proof of principle of small-scale off-grid solar thermal batch recovery of candle wax on the island of Crete in astronomical winter season, where the Sun’s irradiance is in the range of 820–940 W×m−2. The investigation was carried out based on the recovery of unconsumed mixed petroleum-based paraffin and plant-based soy and palm-wax (250 g each) candle fragments and th…

Accurate estimation of solar radiation and optimal tilt angles is essential for maximizing the efficiency and power output of photovoltaic (PV) systems. This study investigates the optimal tilt angles and expected power generation of PV systems across major Syrian cities using climatic and geographical data. Both isotropic and anisotropic solar radiation models were evaluated, with the anisotropi…

Diffusion absorption refrigeration (DAR) is a promising cycle concerning renewable energy utilization, as the cycle can operate using only thermal energy input. However, to realize the benefits of the DAR cycle, there is a need to develop an improved understanding of how design parameters influence its performance. The cycle’s performance was particularly sensitive to several factors: the rate of…

The increasing adoption of electric vehicles (EVs) has highlighted persistent challenges related to battery efficiency, limited lifespan and performance fluctuations during highly dynamic driving conditions. To address such issues, this study proposes a novel Hybrid Energy Storage System (HESS) that strategically combines lithium-ion batteries and supercapacitors to take advantage of the high ene…

Metal film capacitors are ubiquitous components in modern electronics, playing an important role in energy storage, filtering, and voltage regulation. However, their performance and reliability can be reduced by partial electrical breakdowns caused by defects in the dielectric material. An attempt to partially mitigate this problem is the use of self-healing capacitors. The self-healing phenomeno…

The need for clean and renewable energy has grown dramatically over the past few years. As potential candidates for producing green energy in this region, photovoltaic and bio-solar energy technologies have arisen. This review presents a novel approach for designing and developing photovoltaics and bio-solar cells using eco-friendly materials and artificial intelligence (AI) techniques. An intrig…
